Title A name given to the resource Internal validity of a household food security scale is consistent among diverse populations participating in a food supplement program in Colombia Creator An entity primarily responsible for making the resource Melgar-Quinonez Hugo, Hackett Michelle, Uribe Martha Description An account of the resource Abstract Objective We assessed the validity of a locally adapted Colombian Household Food Security Scale (CHFSS) used as a part of the 2006 evaluation of the food supplement component of the Plan for Improving Food and Nutrition in Antioquia, Colombia (MANA – Plan Departamental de Seguridad Alimentaria y Nutricional de Antioquia). Methods Subjects included low-income families with pre-school age children in MANA that responded affirmatively to at least one CHFSS item (n = 1,319). Rasch Modeling was used to evaluate the psychometric characteristics of the items through measure and INFIT values. Differences in CHFSS performance were assessed by area of residency, socioeconomic status and number of children enrolled in MANA. Unidimensionality of a scale by group was further assessed using Differential Item Functioning (DIF). Results Most CHFSS items presented good fitness with most INFIT values within the adequate range of 0.8 to 1.2. Consistency in item measure values between groups was found for all but two items in the comparison by area of residency. Only two adult items exhibited DIF between urban and rural households. Conclusion The results indicate that the adapted CHFSS is a valid tool to assess the household food security of participants in food assistance programs like MANA.

Creator An entity primarily responsible for making the resource Valdir Serafim Jr, Adriana Maria De Grandis, Fabiola Graciele Besen, Tércio Vieira de Araujo Description An account of the resource Foram identificados em relação às unidades de agricultura familiar de municípios da Região Costa Oeste do Paraná, com base em diagnósticos levantados pela ADEOP – Agência de Desenvolvimento do Extremo Oeste do Paraná, entre os anos de 2010 e 2012, as suas principais atividades produtivas, seus prováveis riscos ambientais e situação de dejetos, as condições de seus equipamentos e instalações e suas metas futuras; em relação aos municípios foram levantadas informações sobre as visões municipais relacionadas à agricultura familiar e seus canais de comercialização. A pesquisa caracteriza-se como exploratória e descritiva quanto à tipologia, dedutiva em relação ao método e com abordagem quali-quantitaiva. Conclui-se que, na região estudada, existem vários desafios para o desenvolvimento da agricultura familiar: na dimensão ecológica, por riscos ambientais apurados, nas dimensões econômica e social, pela prevalência de sistemas produtivos convencionais e falta de canais de comercialização, na dimensão cultural pela perda dos saberes locais e cultura regional.

Title A name given to the resource Proposta de aumento da capacidade de tratamento e melhoria da qualidade do efluente da ete de Campina Grande-PB usando a combinação uasb e lagoas de polimento Creator An entity primarily responsible for making the resource Adrianus van Haandel, Silvânia Lucas dos Santos Description An account of the resource Nos artigos anteriores desta série, mostrou-se que sistemas de lagoas de estabilização (LE) apresentam desvantagens que podem ser reduzidas ou mesmo eliminadas quando se substitui a configuração convencional (lagoa anaeróbia/lagoa facultativa/lagoas de maturação) por um sistema composto de um reator UASB seguido por Lagoas de polimento (LP). Essa substituição possibilita o aumento da capacidade de tratamento, melhora a qualidade do efluente, reduz o tamanho e consequentemente os custos de construção, além de permitir a captura do biogás e o aproveitamento do lodo como biofertilizante. Como exemplo, analisaram-se as vantagens de aplicar o reator UASB seguido de LP em substituição ao sistema convencional de LE que se encontra em operação na cidade de Campina Grande, Paraíba. A atual ETE de Campina Grande é constituída por duas lagoas anaeróbias, duas lagoas facultativas e quatro lagoas de maturação, com capacidade para tratar 13.000 m3/d. A análise mostrou que todas as vantagens do novo sistema podem ser materializadas no caso de Campina Grande. Quando se substitui o sistema convencional pela nova alternativa, a capacidade de tratamento da ETE, com a infraestrutura existente, aumentaria para 40.000 m3/d se o efluente fosse utilizado para fertirrigação ou 20.000 m3/d se o efluente fosse utilizado para fins industriais; nesse caso, a remoção de nutrientes é necessária. Assim, todo o efluente seria utilizado de maneira produtiva e não haveria mais descarga nas águas de superfície.

Title A name given to the resource Levantamento populacional de percevejos e da incidência de parasitóides de ovos em cultivos orgânicos de soja Creator An entity primarily responsible for making the resource Régis Sivori Silva Santos Description An account of the resource O presente estudo tem como objetivos identificar as espécies e os níveis populacionais de percevejos-praga e de seus parasitóides de ovos em campos de soja sob manejo orgânico. O estudo foi realizado no ano agrícola 2004/05 em três lavouras de soja sob cultivo orgânico localizadas nos municípios de Três de Maio, São José do Inhacorá e Três Passos no estado do Rio Grande do Sul. Em cada lavoura demarcaram-se duas parcelas de 1800 m2 que consistiram as unidades experimentais. Populações de percevejos foram monitoradas por amostragens semanais com pano de batida em seis pontos aleatórios em cada parcela. Paralelamente foram vistoriadas seis plantas aleatórias e coletadas todas as posturas de percevejos existentes. Foram coletados 400 percevejos, a espécie Piezodorus guildinii foi a mais freqüente (53,75%), seguida de Nezara viridula (17,75%), Dichelops furcatus (12%), Edessa meditabunda (7%) e Acrosternum impicticorne (4,75%). Dos 2660 ovos coletados, 153 (5,75%) estavam parasitados e de 87 (56,86%) emergiram parasitóides. O parasitismo ocorreu apenas em posturas de N. viridula, D. furcatus e A. impicticorne., Registrou-se a ocorrência de cinco espécies de parasitóides: Trissolcus basalis, Trissolcus urichi, Trissolcus brochymenae, Telenomus sp. e Telenomus podisi.

Title A name given to the resource The effect of intrinsic soil properties on soil quality assessments Creator An entity primarily responsible for making the resource Ricardo Simão Diniz Dalmolin, Alessandro Samuel Rosa, Pablo Miguel, Jovani Zalamena, Deborah Pinheiro Dick Description An account of the resource The assessment of soil quality is based on indicators and indices derived from soil properties. However, intrinsic soil properties may interfere with other soil properties that vary under different land uses and are used to calculate the indices. The aim of this study was to assess the extent to which intrinsic soil properties (clay and iron oxide contents) explain variable soil properties (sum of bases, potential acidity, organic carbon, total porosity, and bulk density) under different land uses (native forest, no-tillage and conventional agriculture) on small family farms in Southern Brazil. The results showed that the five properties evaluated can be included in soil quality assessments and are not influenced by the clay and iron oxide contents. It was concluded that for little weathered 1:1 and 2:1 phyllosilicate rich-soils, if the difference between the maximum and the minimum clay content under the different land uses is less than about 200 g kg-1 and the iron oxide content less than about 15 g kg-1, the physico-chemical soil properties in the surface layer are determined mostly by the land use.

Title A name given to the resource Los derivados financieros, su impacto en la seguridad alimentaria y los intentos de regulación Creator An entity primarily responsible for making the resource Antonio Marquina Description An account of the resource Las consecuencias de la especulación con derivados financieros en la seguridad alimentaria se han ido progresivamente clarificando. El artículo enfatiza la excesiva especulación y la desregulación que se produjo a partir del año 2000, señalando que los factores que afectan a la oferta y la demanda no pueden explicar por sí solos la extremada volatilidad y la subida de los precios producida desde 2007. La financiarización de los mercados agrícolas impide que agricultores y comerciantes utilicen el mercado de futuros como una forma de seguro tal como habían venido haciendo y perjudica muy seriamente a los consumidores, especialmente en los Estados más pobres. En otro orden, una alta volatilidad de precios agrícolas conduce a menores beneficios de la producción agrícola, desalienta la inversión, la innovación y la búsqueda de una mayor productividad en la agricultura. El artículo explica los procesos de regulación realizados en Estados Unidos y la Unión Europea, así como el papel del G-20.

Title A name given to the resource Tolerancia de papas nativas (Solanum spp.) a heladas en el contexto de cambio climático Creator An entity primarily responsible for making the resource Doris Marmolejo Gutarra, Jerson Eleazar Ruiz Velásquez Description An account of the resource With the objective of identifying varieties of native potatoes with tolerance to frost,research was carried out in three localities of the central highlands of Peru: Pahual andPaltarumi (Pariahuanca), Huancayo, and Huayllacancha (Yanacancha), Chupaca, Junín.The population consisting of 10 varieties was installed by completely randomized blockdesign. Morphological characters and frost severity were evaluated. The results show thatthe varieties that showed tolerance to frost in the three localities were Yana huancuy(Solanum chaucha), Chaulina (S. phureja), Huamantanga blue (S.chaucha), Camotillo andPeruanita (S. goniocalyx), which presented two layers of palisades of leaf parenchyma, verythick leaves with rough relief and purple stem. In number of stomata, Yana huancuy(Pahual), Chaulina (Paltarumi), Chaulina (Yanacancha) and Chaulina (Combined) stood outwith 7.25; 7.29; 7.18 and 7.22 stomata per optical field, respectively. In percentage ofseverity of the damage by frost, those of smaller damage were Chaulina (Pahual) andCamotillo (Paltarumi) with 14.81 and 14.57%, respectively. It is concluded that the frosttolerant varieties had two palisade layers of the parenchyma and greater thickness withrough relief in leaves, greater number of stomata and stems with purple pigmentation;these morphological characters consider in the genetic improvement of the potato.
